An internal tube 21 and a plurality of clamping blocks 22 surrounding the internal tube 21 are provided at the center of the end surface of one side of the threaded tube 20 relative to the connector 13. The plurality of clamping blocks 22 are arranged along the circumferential direction. One end of the flexible tube 31 is sleeved outside the internal tube 21 and limited between the plurality of clamping blocks 22. The screw cap 19 is threadedly connected to the threaded tube 20 and an insertion hole 23 adapted to the diameter of the flexible tube 31 is provided at one end of the screw cap 19 away from the connector 13. In this embodiment, the adapter sleeve 18 can be threaded, plugged or clamped with the connector 13. The installation method is diverse and determined according to actual conditions.

[0034] A filter 14 is installed in the inner shell 12 . The filter 14 is a prior art and can be purchased according to actual conditions and can be optionally installed in the inner shell 12 .

[0035] The reel 5 is rotatably matched with one end of the inner shell 12 , a mounting cavity 15 is provided inside the reel 5 and a through hole 16 communicating with the mounting cavity 15 is provided on the outer wall of the reel 5 , the flexible tube 31 is pulled out from one end of the connector 13 and passes through the through hole 16 and is wound around the outer wall of the reel 5 .

[0036] The extender body 1 comprises an upper shell 24 and a lower shell 25 which are assembled with each other, and the inner shell 12 is integrally formed with the lower shell 25 . The extender body 1 is provided with a water inlet pipe 26 which is connected with the inner shell, and an internal threaded hole is provided in the water inlet pipe 26 .

[0037] A long circular hole 27 and a plug-in part 28 located at one end of the long circular hole 27 are provided at a position corresponding to the water outlet end 3 on the extender body 1. The plug-in part 28 is fixed or integrally formed with the extender body 1. A slot 29 is provided on one side of the plug-in part 28 facing the long circular hole 27. An outer joint 30 that forms a plug-in fit with the slot 29 is provided at one end of the flexible pipe 31 located outside the long circular hole 27. The outer joint 30 is limited outside the long circular hole 27. In this embodiment, the outer joint 30 can be used as an independent joint or as a adapter. External threads can be provided on the outer wall of the outer joint 30 for threaded connection with other products, and devices such as an external bubbler or a nozzle can be connected. During use, the outer joint 30 is moved along the length direction of the long circular hole 27 to separate the outer joint 30 from the plug-in part 28, and then the flexible pipe 31 can be pulled outwards. Conversely, when the flexible pipe 31 is released and the outer joint 30 is reinstalled into the plug-in part 28 in the opposite direction, fixation is achieved.
